I have a 07 G35x... a few weeks ago the alternator went out, sypmtoms I had: battery light, brake light and no throttle response unless in park or neutral. I replaced it with a used one that only lasted about 2 weeks or so. every since then I have put 2 more used alternators (both tested good at the local AutoZone ) but nothing will keep the battery charged. I have replaced the connector and the battery but she still will not charge, I've been thinking about putting a new belt on it but I doubt that will help.. I've seen other forums of this same issue where the owner just kept putting new alternators on until one seemed to work. I need help. someone please help me. I have a dealer level scan tool if that helps.


are all the g alternators interchangeable or no?

I also have a surging idle issue that came after cleaning TB and installing K&N intakes but I'm more concerned of the voltage issue at the moment.


also I left off the little metal on the back where the harnnes clips on.. dose that have any effects on the alternator?
